Answer:

E all real values of x

Step-by-step explanation:

g(x) =(x+6)/2

There are no limits as to what the value of x can be so the domain of x is all real numbers

The price of a gallon of unleaded gas has dropped to $2.83 today. Yesterday's price was$2.89 . Find the percentage decrease. Rou

alexandr1967 [171]

Decrease = initial price - final price

% decrease = [ (initial price - final price) / initial price ] *100

% decrease =[ (2.89 - 2.83) / 2.89] * 100 = 2.08, which can be rounded to 2.1

Answer: 2.1 %

6+b/b is an integer number. find all possible integer values of b

Andrei [34K]

Step-by-step explanation:

(6+b)/b = x (= an integer number)

6 + b = bx (= still an integer number)

6 = bx - b = b(x - 1) (= still an integer number)

b = 6/(x - 1) (= still an integer number)

now for b to be integer, (x-1) must be a factor of 6 (6 must be divisible by x-1 with 0 remainder).

and integer includes negative numbers too.

the factors of 6 are therefore

1, 2, 3, 6, -1, -2, -3, -6

so, b can be 6/±1 = ±6

b can be 6/±2 = ±3

b can be 6/±3 = ±2

b can be 6/±6 = ±1

so, all possible values for b are also the listed factors of 6 :

-6, -3, -2, -1, 1, 2, 3, 6

Find the measure of angle 2.

raketka [301]

Answer:

$m\angle 2=58^o$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

step 1

Find the measure of arc BC

we know that

$arc\ AB+arc\ BC+arc\ AC=360^o$ ----> by complete circle

substitute the given values

$156^o+arc\ BC+88^o=360^o$

$244^o+arc\ BC=360^o$

$arc\ BC=360^o-244^o=116^o$

step 2

Find the measure of angle 2

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle 2=\frac{1}{2}[arc\ BC]$

substitute

$m\angle 2=\frac{1}{2}[116^o]=58^o$

Given f(x)=2x^2+8 and g(x)=5x-6, find each function. (f+g)(x) (f*g)(x)

liq [111]

$f(x)=2x^{2}+8 \\ \\ g(x)=5x-6 \\ \\ (f+g)(x)=2x^{2}+8+5x-6=2x^{2}+5x+2 \\ \\ (f*g)(x)=(2x^{2}+8)(5x-6)=10x^{3}-12x^{2}+40x-48$
